What is the policy about VPN usage before the exam?

• A. Use a VPN only if instructed.
• B. Leave it enabled for security.
• C. VPN usage has no impact on delivery.
• D. Disable it, as it can impact the performance of the exam delivery software.

Answer: (D)

The main idea is that the exam delivery system needs a stable, direct connection, and VPNs can interfere with that performance. VPNs route traffic through external servers, which adds latency, can alter IP information used for authentication and proctoring, and may cause timeouts or miscommunication with the delivery software. Disabling the VPN before starting ensures a smooth, reliable connection and proper monitoring during the exam.

That’s why this option is the best: it directly addresses preventing performance issues with the exam delivery software. The other choices imply keeping VPNs on for security, or only using them under certain instructions, or claim VPNs don’t affect delivery, all of which can lead to connectivity or verification problems during the exam.
